Plugged in not charging on Dell Inspiron 1525


your answer to your problem lies here.

http://www.howtomendit.com/answers.php?id=141277


If you have the battery at a low level and it's not charging then i think i might have worked out what might be the problem:

First flash the BIOS to Revision A17 (or later if available)
Then power off and turn on the laptop with AC adaptor plugged in, hit F2 to go into BIOS and go to Battery Info.

If you can see 'AC Adapter 65w' at the bottom then there shouldn't be anything wrong with your power supply or the laptop. If it says 'Unknown' then there's a problem with your motherboard or the AC adapter.

Dell Inspiron 9400 will not charge - AC adaptor not recognised


Does the laptop power up just no charge the battery? If the laptop does not power on then you may have a bad power supply in the unit. If it does power up than you most likely have a bad battery connector of blown fuse on the motherboard. The flashing of the BIOS is done with a bootable cd or floppy but this will not keep the new battery from charging. The reason Dell states that you need at least 10% battery to flash a BIOS is because if your AC power goes out while you are doing a BIOS upgrade and you don't have battery power the BIOS will be incomplete and your laptop will not boot again without replacing the motherboard.

Ac adapter does not connect to battery


You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad

New Dell battery, new AC adapter(not Dell). Won't charge battery


Dell uses a proprietary SMBus protocol over the center pin to communicate the type and power capability of the attached adapter. The laptop uses this information to determine if it can charge the battery without browning out the motherboard. If you use a knock-off power supply that doesn't communicate properly (or at all) over SMBus, then the computer will complain and won't charge the battery. Sorry, Dell has us all right where they want us. Find a used actual Dell adapter on eBay for $20 if you can.

Dell Inspiron 8100 won't boot


Send it in to a repair facility, usually runs 80-130 online through ebay. Inspirons are known for blowing fuses/resistors. This may have happened, but either way if you pull the new battery and it dont work still with charger or vice versa you have a power issue on the motherboard.

Good Luck!

Battery will not charge


Hi!

It's your ac adapter that is causing this issue. The ac adapter doesn't supply enough power or doesn't supply any power at all to the battery. Try to borrow another ac adapter from any inspiron system and if that works, then you need to replace the ac adapter, else, it's the motherboard.

Hope you find it helpful.

Thanks,

Karlox™ :)
